General Electric THQB2170 Miniature Circuit Breaker

The GE THQB2170 is a two-pole miniature circuit breaker designed to interrupt current in two conductors when an electrical fault occurs. It is rated at 70 amperes and is specified for operation at both 50 Hz and 60 Hz, making it suitable for regional electrical systems that use either frequency. As part of GE’s THQB family, the THQB2170 provides automatic protection by opening the circuit when overcurrent is detected, helping to prevent damage to wiring and connected equipment. This model is intended for installations that require a 2-pole, 70 A protective device, common in commercial and light-industrial distribution paths where reliable protection of feeders and branch circuits is necessary. The 50/60 Hz specification reflects versatility across markets, while the 2P configuration ensures simultaneous disconnection of both conductors in the protected circuit. When selecting a replacement, verify that the panel is designed to accept THQB-series breakers and that the 2P, 70 A, 50/60 Hz requirements match the circuit's design parameters.
